    Synthesis of 4-(thien-2-yl)-substituted coumarins through Lewis acid catalyzed Michael addition of thiophenes to 3-benzoylcoumarins followed by oxidation [Electronic resource] / R. A.

THIOPHENES -- 3-BENZOYLCOUMARINS -- Lewis acid
Аннотация: 3-Benzoyl-4-(thien-2-yl)coumarins have been obtained in good yields according to the SNH addition–oxidation protocol, involving the diastereoselective addition of thiophenes at C-4 of 3-benzoylcoumarins under BBr3 catalysis, followed by oxidation of the intermediate 3,4-trans-3-benzoyl-4-(thien-2-yl)-3,4-dihydrocoumarins with DDQ. This two-step procedure can be regarded as nucleophilic substitution of hydrogen (SNH) on the heterocyclic ring of coumarins

Аннотация: A series of [(2-dimethylamino)ethylamino]methylidene-1,3-dicarbonyl compounds was synthesized for the first time starting from the corresponding 2-ethoxymethylidene derivatives and N,N-dimethylethylenediamine. It was shown that further alkylation of aminomethylidene derivatives with methyl iodide occurs regioselectively at the tertiary nitrogen atom. Quaternization products obtained exhibit high corrosion inhibition of mild steel in hydrochloric acid medium

CONGENERS -- DESCRIPTORS -- ELECTROPHILIC SUBSTITUTION
Аннотация: To explain the chemical reactivity of polychlorinated biphenyls in nucleophilic (SN) and electrophilic (SE) substitutions, quantum chemical calculations were carried out at the B3LYP/6-31G(d) level of the Density Functional Theory in gas phase. Carbon atomic charges in biphenyl structure were calculated by the Atoms-in-Molecules method. Chemical hardness and global electrophilicity index parameters were determined for congeners. A comparison of calculated descriptors and experimental data for congener reactivity in the SN and SE reactions was made. It is shown that interactions in the SN mechanism are reactions of the hard acid-hard base type, these are the most effective in case of highly chlorinated substrates. To explain the congener reactivity in the SE reactions, correct descriptors were not established. The obtained results can be used to carry out chemical transformations of the polychlorinated biphenyls in order to prepare them for microbiological destruction or preservation

Аннотация: Triterpene derivatives with an α,β-alkenenitrile moiety in the five-membered ring A have been synthesized by nitrile anion cyclizations of 1-cyano-2,3-secotriterpenoids. Oxime-containing precursors, 2,3- secointermediates and five-membered ring A products of cyclizations were screened for in vitro antiviral activity against enveloped viruses - influenza A virus and human immunodeficiency virus type I (HIV-1). Lupane ketoxime and the 2,3-secolupane C-3 aldoxime which possess antiviral activities against both influenza A virus (EC50 12.9-18.2 μM) and HIV-1 (EC50 0.06 μM) were the most promising compounds.

Аннотация: N-Containing perfluoropentanoic acid derivatives were used as modifying additives to commercial epoxy resins. As shown by differential thermal analysis, the fluorinated organic derivatives exhibit catalytic activity in curing of epoxy resins. The following characteristics of the adhesive compounds in the cured state were determined: degree of swelling, gel fraction content, ultimate shear strength of the adhesive joint, adhesion to low-carbon St.3 steel and AMg-6 aluminum-magnesium alloy, and corrosion-protective properties with respect to these materials

POLYCHLORINATED BIPHENYLS -- SOVOL MIXTURE -- NUCLEOPHILIC SUBSTITUTION
Аннотация: In order to comprehend the data on reactivity of polychlorinated biphenyls of the Sovol mixture in nucleophilic substitution reactions we have performed quantum-chemical simulation using the RB3LYP\6-31G(d) gas phase approximation. Using the "Atoms-in-Molecules" approach, we have computed charges on the biphenyl carbon atoms adjacent to chlorine; furthermore, absolute chemical hardness and global electrophilicity index have been determined for the studied chlorobiphenyls. The calculated descriptors have been correlated with experimentally determined reactivity of the biphenyls in the hard acid-hard base nucleophilic reactions. The higher reactivity of more chlorinated substrates has been confirmed
